TIME DAMPENED CHARGING INDICATOR
First Claim
1. A method for determining a charging state, the method comprising:
- performing the following with a processor;
estimating a difference between a first power pack capacity of a power pack at a first time and a second power pack capacity of the power pack at a second time, the second time being a time duration after the first time;
determining, based upon the difference, a direction of change of power pack capacity of the power pack; and
displaying, in response to estimating the difference, a respective charging indicator that reflects the direction of the change.

Abstract
Systems and methods to determine a power pack charging state. A difference between a first power pack capacity of a power pack at a first time and a second power pack capacity of the power pack at a second time is estimated, where the second time is a time duration after the first time. A determination is made that the charging state is “not charging” if the power pack capacity decreases between the two times. A determination is made that the charging state is “charging” if the power pack capacity increases between the two times. If a change in power pack capacity is not observed between the two times, the power pack charging state of the previous determination is used. Various techniques are used to determine the difference in power pack charging state.
